Photograph of the San Fernando Reservoir, showing large cylindrical tower in foreground, [s.d.]. In the extreme foreground at left, a large cylindrical tower can be seen. Several small holes can be seen on the exterior of the object. The top of the structure is ridged, and small teeth can be seen on the upper rim. A wire appears to be connected to the top of the tower and extends to the left. Beyond the tower, a large expanse of water can be seen extending into the extreme background. At center, two stone jetties are visible in the water. In the extreme background, large grassy mountains can be seen extending from left to right. Caption on the side of the image reads: "San Fernando Reservoir, Thirty Miles From Los Angeles".
